I Have A Program Which I Want To Run
The Problem Is I Need To Change The Registry For The Program To Work.
My Problem Is That I Cant Change The Registry From Certain Computers.
Now Being A Fan Of Portable Apps I Thought That Maybe Portable Apps
May Offer Me A Solution.

The Only Thing I Need Is Some Sort Of Explanation On How To Make A Launcher For A Program That Will Save These Registries And Execute The File Then Possibly Delete The Registries That I Need.There Is One More Thing One Of The Registries Values Is Supposed To Be A File Path Which Is In The Program-Is There Some Simple Way To Make A Dynamic Registry?
